Spatial Interactions In Monobath Development, Gary Mcsweeney
Theses
The sensitometric effects of varying developing agent concentration, fixing agent concentration, and pH in a monobath developer were studied with Kodak Tri-X Pan film. Three variables (gamma, base plus fog, and a shoulder density) were studied under varying levels of each of the factors. A factorial experiment was run and an analysis of variance (ANOVA) was used to determine whether or not each of the main factors and the two-factor interactions were significant. The higher order interactions were used as a measure of experimental error for the analysis. In the range of the factors being investigated, it was found that: …

Wet Film Sensitometry With An Infrared Scanning Densitometer, Anthony Casinelli, John Hisler
Theses
This project was to design and operate an infrared scanning densitometer to monitor the growth of the characteristic curve of a film during development. An aparatus was constructed which enabled us to pass repeatedly, a sensitometric strip through a beam of radiation during development. This radiation was focused on the film plane of the development container. The spot on the film plane was relayed, after transmission through the sample, to a photomultiplier tube. The response of the tube was displayed an oscilloscope and this was photographed. We were able to obtain a trace of the characteristic curve of a fully …
